4.  How to Fry a Wireless Router or Two

I had a phone call last week from my brother, who was having internet connection problems with his wireless computers after a lightning storm. The lightning storm had fried both of his wireless routers. It had happened before, too...

First, let's talk about his physical layout, which has a lot to do with the lightning damage problem. Next week, we'll look at the network configuration problem that kept him from getting back online.

He lives outside of town, where he was able to get plenty of land. His office is about 250 feet from the house. It's where his Internet connection arrives. He has a wireless router at that office. There's a desktop computer connected directly (via Ethernet cable) to the wireless router.

The house also has a wireless router, to provide easy access for his notebook computer. The house wireless router also has a desktop computer directly connected to it via Ethernet cable. The house wireless router connects via Ethernet to the router at the office — about 250 feet away.

There lies the situation causing the router damages. That long run of Ethernet cable is within the Ethernet maximum distance specification (100 meters = 330 feet).

However, it runs through a shallowly buried underground conduit. That means that it is susceptible to electrical shocks caused by lightning in the area — much more susceptible than the house wiring or Ethernet cable in the house or office.

In effect, the reason he keeps losing wireless routers (or routers of any kind), is that they're acting as expensive fuses — expensive, non-resettable circuit breakers!

The Ethernet cable, from the office to the house, connects through these two devices.

So far, I know he's had Linksys, DLink and now Belkin routers.

This time, not only did he fry two routers, he also lost the motherboard on one of the computers that was connected by Ethernet to one of the two routers.

What's the right solution?

Since he's demonstrated the vulnerability caused by the long, buried Ethernet cable, I think he needs to add surge protection on both ends of that Ethernet cable. Both ends are needed because he has computers and routers at both ends of the cable.

I did a quick search and found these options for Ethernet surge protectors.

5.  My Computer Security Software Recommendations

I review my security software recommendations and update them for each weekly newsletter issue, if I think they need to change.

My Philosophy: Many people want to pick their most economical solution and prefer an all-in-one anti-virus, anti-spyware and firewall solution. In concept, that's a great idea. In actual practice, I don' think that this type of package is likely to be the best in all the protection categories you need.

Other people want to pick the best of each type program. I'm one of the these folks.

My choice of software that I am willing to recommend is driven by my search for software for me to use. I only recommend programs that I like and that I use. I will sometimes suggest alternatives to my recommendations, but I clearly note if I no longer use them.

Anti-Virus

I'm often asked about several other popular anti-virus or anti-virus combination packages. Yes, I realize that they are not in my recommendation list. "Enough said..."

From 2003 through mid-2008, my personal choice was ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I still consider NOD32 to be one of the best in anti-virus protection — and it continues to get recognition and awards. Unlike some of its competitors, ESET offers multiple-year licenses also, and includes program updates in the multiple-year license.

However, I've changed from my long-time choices NOD32 (antivirus) and Sunbelt's CounterSpy (antispyware) to Sunbelt's new VIPRE Antivirus + Antispyware.

I've found that VIPRE puts even less load on my computer than the speedy combination of NOD32 and CounterSpy. I've also been impressed with the way its "deep scan" has found and eliminated risks that were stored in zip files, which is one of the latest malware email tricks. Sunbelt Software offers multi-year licenses and home site licenses on its software, both of which include program updates as well as signature updates.

I'm often asked for alternatives to the programs that I recommend, especially by people who want to buy one package to do everything.

I tried a couple security suites in the last few months to pick a suite to recommend. ESET Smart Security 4 is my recommended suite alternative. Smart Security 4 has gotten great ratings and includes antivirus and antispyware, both from their current NOD32 v4 version, and antispam and firewall. I no longer use it and have returned to Sunbelt's VIPRE, but for a suite choice, that's what I would use.

Firewall Software

While the Windows XP firewall is much better than no firewall at all, don't count on the Windows XP firewall to meet your needs.

You need a two-way firewall, which the Windows XP firewall is not!. Microsoft woke up and supplied a two-way firewall with Windows Vista.

The Windows XP firewall does not control outbound communications originating from your computer — and you should want to have control if adware/trojans/spyware or even commercial products want to talk to the Internet. Whether they are calling home or spewing spam, you want to be able to control your computer.

Do you want Windows Media Player to call home every time you play something? It does! Do you use the Search function in Windows Explorer to find things on your hard drive? Did you know that every time you search, Windows Explorer talks to Microsoft?

I didn't know that when I ran ZoneAlarm, but the Sunbelt Personal Firewall flags that to me, and I can stop it or allow it to happen. Many other programs try to call home when you run them, too.

I recommend my choice for a firewall program, which is Sunbelt Personal Firewall.

You can try the full-featured "paid version" of Sunbelt Personal Firewall free for 30 days — after that, you can register it or, if you're using it on a home non-business computer, you can let it revert to the free, lesser-function license.
Tip: Be sure to read my review of SPF for the settings I recommend.

Sunbelt Personal Firewall is regularly $19.95 (with discounts for multiple computers and/or multiple years!) for a non-expiring license for the program and includes one year of their updates subscription.

Anti-Spyware / Anti-Adware Software

CounterSpy, from Sunbelt Software, has received many kudos from the computer press for its always-running and periodic full system scans. It has been my personal choice for my PC's and my family's PC's.

Sunbelt's CounterSpy v2.5, both improved CounterSpy's performance against malware and reduced its impact on system resources and responsiveness when its scanning.

Sunbelt continues to release updated program versions — the current version is v3.1 — and there's an even newer version about to be released. Nicely, Sunbelt do NOT install the updated programs automatically. You have to use the Update process in the program, which means that you'll know that something significant has changed.

Now, I've changed from my long-time programs NOD32 (antivirus) and CounterSpy (antispyware) to Sunbelt's new VIPRE Antivirus + Antispyware.

I've found that VIPRE puts even less load on my computer than the speedy combination of NOD32 and CounterSpy. My computer seems to have much more pep and power than it had previously. I've also been impressed with the way its "deep scan" has found and eliminated risks that were stored in zip files, which is one of the latest malware email tricks.

Anti-spam Software

In today's Internet world, the question is not "if" you will get spam, but "how much will you get?"

I use and recommend POPFile as my first choice for handling spam. POPFile sits on your computer, between your email program and your ISP mailbox, and handles emial as it downloads.

POPFile uses a different approach to handle spam than some other programs do — it does nothing to reduce spam. It is designed as an email classification tool — you train it to recognize spam and any other type of email that you want to classify. These classifications can help you sort your emails into appropriate folders in your email program.

Sunbelt Software, who makes the anti-spyware program CounterSpy (which I use and recommend) and the firewall that I use and recommend (Sunbelt Personal Firewall) also has a well-regarded, award-winning anti-spam program called iHateSpam for Outlook and Outlook Express. Since I don't use Outlook or Outlook Express for email, I haven't tried iHateSpam.

Mailwasher Pro would be my first choice to handle spam before it ever gets into your computer's Inbox. Mailwasher Pro uses on-line Realtime Black Lists mail servers sending spam recently, "training" by you of what you think is spam, and your own "friends" and "blacklist" lists. Note: I found that PopFile generally meets my needs and stopped using Mailwasher Pro, even though PopFile works AFTER the emails have been downloaded. If I used a dialup connection, I would be more interested in Mailwasher Pro.

Mailwasher Pro can even bounce spam messages, as if your email address was not valid, although the usefulness and appropriateness of this is questionable. There is a free version called "Mailwasher," but it omits the functions that I consider critical for this purpose -- such as safely previewing the emails safely before they ever get to your email inbox.

Cable/DSL Router

If you have a cable modem or a DSL modem, you need to have another layer of inexpensive protection between you and the Internet. A cable/DSL router isolates your computer from direct connection to the Internet. Your computer can easily request your email, web pages, etc. through the router. The responses come back to the router and are smoothly routed to your computer. But, someone on the Internet side of the router can not initiate a connection to your computer — they can only respond to your request.

Even if you only have one computer to connect to your cable or DSL modem, I recommend that you purchase and use a cable/DSL router because of the protection it can give you against attempts to attack through some flaws in Windows itself.

A router isolates your local network, whether it is only one computer or several, from the Internet by actually making it a separate network. The router gets the "public" IP address and handles all your outbound communications and the responses to them. But, it blocks computers on the Internet side from being able to initiate communications with your computer! This will prevent you from falling prey to many worms that try to attack security holes in Windows itself.

For a wireless router, I recommend the Linksys WRT54G wireless router. I'm using the relatively new version 6 of this router.

If you don't want wireless, I recommend the Linksys BEFSR41 wired router, which I also use. Either way, based on my experience, I recommend Linksys routers for price, reliability and Linksys' habit of releasing updated firmware for their products..
